On-Board Computer
Some functions of the on-board computer display are linked with the data of the navigation unit: The time is set automatically according to the data determined by the GPS receiver; thus, the only work required involves setting the time zone once.
The route to the destination is known if the route guidance function is activated in the navigation unit. The length of this route is displayed as the distance to the destination. The range display
allows an estimate about whether the fuel supply is adequate for the remaining distance. The estimated time of arrival is calculated on an individual basis according to the driving style and the planned route: The navigation unit informs the on-board computer about the different road categories along the route and the length of
these road sections.
The on-board computer calculates a different individual average driving speed for each road category. This information is used to calculated the planned time of arrival - if no traffic-related delays occur - on an individual basis.
The on-board computer also supplies standard information, for instance the average consumption, average speed, distance travelled, and elapsed driving time. The outside temperature is adopted from the instrument cluster. It is possible to set a limit that triggers a visual and audible speed warning.
It is also possible to switch to different units of measure and languages and adjust the display contrast.
The A/C function is limited to the display of data transferred from the air-conditioning regulator.
- Fan setpoint
- Passenger compartment temperature setpoint
- Air distribution
- Status display (automatic system, defroster, A/C compressor, air circulation)
The display is activated automatically whenever a manual adjustment is made on the air conditioning regulator or the A/C function is specifically selected.
